Canon 650D/T3i jerky video when sliding at DVinfo.net

Hi all,

I am using a Canon EOS650D on a slider and most of the shots are jerky...as if there is some kind of image stabilisation at play trying to compensate for the sideways movement of the camera. The lens I am using does not have IS - a TAMRON 18-200mm AF. The jerky motion doesn't show up clearly on the LCD when I am shooting (sometimes it does) but the jerkiness is indeed quite bad.

Is there some kind of internal image stabilisation on a 650D that can be turned off? I can't find any info on it anywhere.

I know I am getting older, but surely I can't be getting THAT shaky!! :-)

Cheers,

David

No. You need a lens with IS, first of all.

2nd, the T3i is just a light camera, so it's going to jerk and shake more than heavier cams when you move it, On a slider with an IS lens, this will mean you can't use the first and last second of the glide when you push it because it will still be reacting to the force. Same reason we dumped the cheaper tripods... they were too stiff to move and the cameras kept shaking.

It does show up on the LCD, it's just that the LCD is so small it's hard to notice. Anything you spot in LCD will be magnified by many orders once it's on a TV 10-20 times bigger. You see some folks get a 7" external monitor to help with that - it also makes manual focus easier.

Thanks Robert.

I thought perhaps I had missed something in the settings somewhere (that I couldn't find).

I had a 550D and used it with the same slider for a couple of years and didn't suffer this problem.

it really does look like a stabiliser is trying to compensate for the movement.

Anyway, thanks for your info.

No, you don't necessarily need a lens with IS on it...we use the t3i, 60D and MarkII on sliders with non-IS lenses and its just fine. We use the tamron 17-50 and 28-75 or Rokinon 14mm on a Glidetrack and Konova sliders.Maybe you can add a footage of what the shakiness looks like?

Cheers,

Two thoughts.. how fast are you sliding, and are you using the rubber band trick to provide a consistent force on the pull direction?

I've also had no issues with my t2i unless I jerk the pull myself or go too fast.
